Consumer Response to Climate Change: Wildfire Smoke and Sustainable Product Choice
利用野火烟雾随机扩散作为自然实验，结合零售扫描数据和在线调查，发现暴露于严重野火烟雾的商店对可持续清洁产品的需求短期增加，尤其对补充装和可持续品牌效果更强。
Global warming has increased the frequency and intensity of extreme climate change events. The authors study the impact of severe climate change events, particularly wildfire smoke, on consumer purchases of sustainable products. They exploit the random dispersion of wildfire smoke as a natural experiment and analyze three large-scale wildfires from 2018, 2020, and 2023. They combined retail scanner data with air quality data for the first two events and conducted online surveys for the last event. They show that stores exposed to severe wildfire smoke experience an increased demand for sustainable cleaning products relative to stores facing little to no wildfire smoke. The increase occurs promptly after the wildfire smoke exposure, which is short-lived. The authors also find stronger effects for refill products and sustainable brands. Survey results corroborate and extend the empirical findings by demonstrating the effect of exposure on attitudinal changes. In summary, this study documents the meaningful impact of climate change events on sustainable consumption by analyzing multiple events over the years using a multimethod approach. The study offers relevant and timely managerial insights as consumers are increasingly exposed to more intense and recurrent climate change events.
